Use of the bacterium Pseudomonas aeruginosa to influence the growth and activity of some pathogenic fungi to plant maize, Zea mays. L.

Abstract

Was to isolate and diagnose 5 local bacterial isolates Pseudomonas aeruginosa from 20 soil samples in the Agricultural College of Agriculture, University of Baghdad . Tested their ability to control vital Aftran Fusarium solani and Aspergillus niger nurse Bdhurenbat maize .Outperformed bacterial isolation (AB4) in its ability to inhibit the growth of fungi and F.solani A.niger being of their growth rate was 2.3 mm and 2.4 mm on the two mediums Alzeraaan King-B, PDA , respectively, compared Baezzlat and other treatment comparison as it was the growth of fungi 12 0.20 and 20.35 mm respectively . He studied the effect of bacterial isolates in seed germination presence and absence of pathogens has been shown that vaccination seeds isolated bacterial Pseudomonas aeruginosa led to increase the percentage of germination and protection from the impact of pathogenic fungi , as the percentage of germination of 80% for the fourth day and 60% for the day Xrmen period cuddling compared to other treatments .Extracted compound Alkhalb Iron Alseidrawfor (Siderophore) produced by bacterial isolates then diagnosed amino acids involved in the installation , a leucine and alanine and threonine using infrared technology (FT-IR).
